There is no way to remove old entries on the device unless they are paired. This makes it impossible to remove an entry for a device that someone else paired to bluetooth and you re-pair to the dongle. Now the dongle is full and I can not pair them back to the bluetooth and it won't remove the entry without being able to connect to the device... The old unifying software was able to remove old entries, how it the world is your new software unable to...?
